NAD replenishment restores mitochondrial function and thermogenesis in the brown adipose tissue of mice with obesity

The Journal of Physiology, EarlyView.
Abstract figure legend A high‐fat diet (HFD) induces brown adipose tissue (BAT) whitening, mitochondrial dysfunction (damaged cristae, fragmentation), reduced NAD+ levels and impaired thermogenesis, leading to lower energy expenditure and metabolic inflexibility.

Mito‐TEMPO Improves Post‐Thaw Quality and Fertilizing Capacity of Rooster Semen Cryopreserved in Beltsville Extender

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study reported the effect of Mito‐TEMPO on rooster semen quality cryopreserved in Beltsville extender. Semen diluted in extenders containing 10 or 100 µM of Mito‐TEMPO presented higher motility, average path velocity as well as membrane/acrosome integrity, mitochondrial activity, and fertility rate; and lower lipid peroxidation, apoptosis rate ...

Redox‐Dependent Chaperoning of GBF1 Condensates Regulates Seed Germination in Arabidopsis

Advanced Science, Volume 13, Issue 47, 24 August 2026.
In dormant seeds (low ROS), GBF1 forms liquid condensates to repress the germination gene CathB3, and the chaperone GIP1 maintains condensate liquidity and repressive activity. Upon imbibition (high ROS), ROS oxidize GIP1 during germination, impairing its chaperone function.

Fission product yield measurements using monoenergetic photon beams

EPJ Web of Conferences, 2017
Measurements of fission products yields (FPYs) are an important source of information on the fission process. During the past couple of years, a TUNL-LANL-LLNL collaboration has provided data on the FPYs from quasi monoenergetic neutron-induced fission ...

HNRNPD Induces Radioresistance in Nasopharyngeal Carcinoma by Sequestering GRAMD4 mRNA in Stress Granules

Advanced Science, Volume 13, Issue 43, 3 August 2026.
HNRNPD promotes radioresistance in nasopharyngeal carcinoma by enhancing stress granule assembly and sequestering GRAMD4 mRNA. This suppresses GRAMD4 translation and inhibits mitochondrial apoptosis. Targeting the integrated stress response with ISRIB restores GRAMD4 expression and sensitizes tumors to radiotherapy, revealing a translational control ...

SIRT6‐Mediated Deacetylation of ATF3 Promotes Silica‐Induced Lung Fibrosis by Enhancing its Nuclear Import via Binding to Importin α

Advanced Science, Volume 13, Issue 46, 17 August 2026.
SIRT6‐mediated ATF3 acetylation drives MGARP transcription and mitochondrial dysfunction in macrophages, promoting macrophage senescence and pulmonary fibrosis. Mechanistically, HSP70/Importin α competitively binds to ATF3, modulating its nuclear translocation.
